That's the thing - titanium and steel (and alloys thereof),
do not fail due to fatigue if the stresses are kept low enough, unlike aluminium and magnesium (and alloys thereof), which will eventually fail by fatigue regardless of the magnitude of the stresses.

And all three are used in bikes - 531 is a manganese-molybdenum alloy steel, 4130 is chromium-molybdenum alloy steel, and magnesium alloys have been used for bike frames, so it's no wonder the names are getting hurled about.
